• Channel Bank A Device that carries multiple analog or digital signals between

sites. The Analog and Digital channels are converted to a

64 Kbps channels and known as a DS0, then multiplexes into a

higher speed channel at 1.54 Mbps using a method of Time

Division Multiplexing known as DS1. Then transported as a block

to the remote terminal(s) where they are De-multiplexed and

passed back to the DS0 or channel modules. Usually, the digital

information is put on each DS0 signal using pulse code

modulation (PCM).

• Multiplexer A multiplexer (or mux) is a device that selects one of

several analog or digital input signals and forwards the

selected input into a single line. Multiplexers are mainly

use to increase the amount of data that can be sent

over the network within a certain amount of time and

bandwidth. Generally communicates via Electrical, DSU or

fiber, or microwave radio.
